Ten Ways Police Can Legally Lie to You

[Parapluie]

<i>part of consideration of lie detector tests, is to see if alleged defendant will willingly take the test.  that shows he is foolish nowadays. invoke ur rites for an attorney.

it also makes the alleged perp feel he will clear his name.  and they can move on to the real criminals.

but, anxiety, PTSD, and all sorts of things affect test results.   sociopaths can take a valium or not, and train their body to lie.  they pass tests.</i>

I find myself worrying about this.  I was already pretty tightly-wound before  I developed any disorders like those you mentioned (I'm sorry f that's saying too much in any way), and have always found authority figures intimidating. I tend to look guilty out of plain old fear. I don't expect to do anythng that would get me attached to a lie detector but anything can happen and if I were, it wouldn't look good for me.
Years ago---do you remember seeing anything like this?--there were articles and some discussion showing up* that debated carrying a card like the one they show here: https://iamerica.org/know-your-rights (towards the bottom). I had thought about it but handing out something like that felt a touch (passive)aggressive. If it comes down to basic interaction, a 'how's your day' from a police officer on the street being courteous and choosing my words carefully seems like a better choice.
And thank you!
